Running a VM inside Android

I'm coming up with ideas to fully automate a cellphone, I was able to do it connecting to my computer via adb. But now I want to do something more practical, running the entire automation from phone without the need for a computer.

I tried doing this by building an APP, but unfortunately you can't use Appium and uiautomator without connecting an APP, I've recently discovered you can run Docker on android:

Do you think it's possible to run a VM inside android? I'd then just run my scripts to automate, TikTok/IG/YT w/e..

qemu or bochs
